To provide an excellent in resistance to spotting, to provide a manufacturing method thereof, to provide a lithographic printing plate support and an original plate for lithographic printing plate using the aluminum alloy plate, and, in particular, to provide an on-machine developable original plate for lithographic printing plate.

In the manufacturing method of the lithographic printing plate support, the method for manufacturing an aluminum support for lithographic printing plate comprises: a semi-continuous casting process for forming an ingot from an aluminum alloy melt consisting of Fe of 0.08 to 0.45 mass%, Si of 0.05 to 0.20 mass% and the remainder of inevitable impurities and Al; and respective treatment processes in which a sheet thickness (X) of the ingot after the semi-continuous casting process, a sheet thickness (Y) after a cold rolling process, a surface removal amount (A) on a scalping process, a surface roughening amount (B) removed by surface roughening treatment and a film thickness (C) of an anodized film satisfies inequality (i).
